I am interested in getting a folding bike. I feel overwhelmed by the choices. Does anyone know which bike is best for commuting, possible racing and possible touring and possible dirt paths? I know I have a lot of desires, but mostly I will be street riding/commuting. I am 5' tall. Bike Friday suggested 3 bikes: Pocket Rocket, Tikit, Crusoe. But the cost is high. The Swift sounds interesting, but does not sound like it folds small enough? The Dahon and Citizen both seem also interesting too. I welcome all advise and help.
